Abstract

The invention discloses a preparation process of special carbon for adsorbing automobile exhaust, belonging to the field of activated carbon processing. The preparation process comprises the following specific steps: (1) preparing 100 parts of anthracite, 30-50 parts of an adhesive, 10-20 parts of carclazyte powder, 2-5 parts of calcium nitrate and 1-2 parts of magnesium carbonate; and (2) putting the washed anthracite into a Raymond mill for grinding, and conducting sieving with a 200-mesh sieve to obtain feed coal. According to the invention, columnar strip materials are aired for a long time, so internal stress of the columnar strip materials is fully eliminated, expansion of the columnar strip materials is promoted, coal becomes fluffy, foundation pores are expanded, and a foundation is laid for improving the adsorption effect; and the carclazyte powder is also added, and the carclazyte powder has a large specific surface area, a large pore volume, special adsorption capacity and ion exchange performance, and strong decolorizing capacity and activity, so the activated carbon has enhanced adsorption capacity, can efficiently desulfurize, has high mechanical strength, is suitable for desulfurization and dust collection of automobile exhaust, and is also suitable for recovery of benzene, phenol and high-boiling-point solvents.

Description

technical field [0001] The invention relates to the field of activated carbon processing, in particular to a preparation process of special carbon for absorbing automobile exhaust. Background technique [0002] The main source of urban environmental pollution is the exhaust containing toxic and harmful substances emitted by automobiles. However, with the continuous improvement of people's living standards, the number of urban automobiles has also increased rapidly. Since most automobiles do not have exhaust gas treatment devices, the automobile exhaust Directly discharged into the air, resulting in more and more serious air pollution in cities. The harmful components in automobile exhaust include carbon monoxide CO, nitrogen oxides NOx, hydrocarbons, aldehydes and lead-containing substances, among which formaldehyde is the main formaldehyde , accounting for 60% to 70%. Formaldehyde is an irritating gas that is irritating to the eyes and can also irritate the respiratory trac...
